[Change in the catecholamine balance of rat hypothalamus at late periods following local irradiation and its correction with etimizol].

A local exposure (15 Gy) of chest caused a disturbance in the metabolism of adrenergic mediators of hypothalamus at later times (1-12 months) after irradiation: this was manifested by a decrease in the noradrenaline level 1 month following irradiation, and by phase changes in the dopamine content and considerable deficiency of deoxyphenylatanine throughout the entire period of observation. The treatment with etymisol normalized the catecholamine balance.
